panda3dC++ core
3D game engine developed jointly by Disney and contributors from around the world.
pygame is the classic choice for 2D games in Python, built on SDL, with a long history of tutorials and examples. pygame-ce is a community edition fork that is developed more actively and works as a drop-in replacement (you still import pygame), so new projects often start with it. Arcade is a modern 2D library built on OpenGL with a cleaner object-oriented API, sprites and physics helpers. pyglet handles windowing, OpenGL graphics, audio and input with no external dependencies.
